Thank you very much for your answer Gene.
As you stated,the error will remain as long as the problem is not fixed.
But as this error indicates a "High current" condition, when I started the washer, and the cycle has not started yet, the motor is not energized and so there is no way to have a high current condition. So at that point, the system should show no error. I agree that if the motor is energized, then it may again present a high current condition and the error will come back.
This is excactly what I want to try before ordering a new board.
But in order to do so, I need to reset the errror code.
The Service Manual provides explnation on how to do that, I just can't understand why can't I get in diagnostic mode.
This is the heart of my question.
